Prerequisites

Before starting, ensure the following requirements are in place:

  • System Requirements: A server with a minimum of 2 GB RAM and a dual-core processor.
  • Java Runtime: Install Java 11 or newer on the server.
  • Database: Set up a database such as PostgreSQL, MySQL, or SQL Server for SonarQube.
  • .NET SDK: Ensure the latest .NET SDK is installed on your machine.

Installing SonarQube

Follow these steps to install SonarQube:

  1. Download SonarQube: Visit the official SonarQube website and download the latest version.
  2. Extract Files: Unzip the downloaded file into a directory of your choice.
  3. Database Configuration: Open the sonar.properties file in the conf folder and configure your database settings.
  4. Start SonarQube: Execute the StartSonar.bat (Windows) or StartSonar.sh (Linux) script to start the server.
  5. Access the Dashboard: Open your browser and navigate to http://localhost:9000 to access the SonarQube interface.

Configuring SonarQube for .NET

Once SonarQube is running, configure it to analyze .NET projects:

  • Log in: Use the default credentials (admin/admin).
  • Create a Project: Click “Create New Project,” then specify a unique project key and name.
  • Quality Profiles: Navigate to “Quality Profiles” and customize profiles for .NET if needed.
  • Plugins: Verify that C# and .NET plugins are installed and active.

Setting Up SonarScanner for .NET

SonarScanner is required to analyze .NET projects. Follow these steps:

  1. Download: Get SonarScanner for MSBuild from the official documentation.
  2. Install: Extract the zip file and add the bin directory to your system’s PATH.
  3. Project Preparation: Navigate to your .NET project directory and run: 
    SonarScanner.MSBuild.exe begin /k:"project-key" /d:sonar.login="your-token"
  4. Build: Use MSBuild to compile your project: 
    msbuild YourProject.sln
  5. Analyze: Complete the scan with: 
    SonarScanner.MSBuild.exe end /d:sonar.login="your-token"

Verifying Your Setup

After completing the scan, review your results:

  • Access the SonarQube dashboard and locate your project.
  • Review metrics like bugs, vulnerabilities, and code smells.
  • Use the insights to improve code quality and address issues.

Conclusion

Setting up SonarQube for .NET projects is a straightforward process that yields significant benefits for code quality and security. By following this guide, you can ensure a seamless integration that helps you write better, more secure software.
